The D.C. Metro is Full of “House of Cards” Spoilers

People in large cities love hanging out near the edge of subway platforms despite years of warnings and actual evidence it can be fatal.

Anyone who saw the first few minutes of the latest House of Cards season can attest. One such viewer decided not to let Zoe Barnes die in vain with this helpful caution sign at a Washington, D.C. Metro station.

Good work, anonymous subway rider. You may have just saved a life. Now, look into the camera and deliver a Shakespearian diatribe about your intelligence a la Frank Underwood. You’ve earned it.
